Peripherally inserted central venous catheters in preterm newborns: two unusual complications

This report describes the case of two newborns who suffered unusual complications after peripheral insertion of a central venous catheter. In one baby a fragment of the catheter tip became embolized in a peripheral branch of the left pulmonary artery. In the other baby, the catheter perforated a peripheral branch of the pulmonary artery, giving rise to chemical pneumonitis with extensive pleural effusion. The outcome was positive for both babies. A large clinical series is necessary to establish the complications of this procedure, their prevention and management.
